  1. Assembly Programming with the PicKit ACSE Annual Conference November 2006 Erin Lester

  2. Microchip’s PicKit • USB flash microcontroller programmer • Costs approx. $30 US • Can be programmed in C++ or Assembly • Comes with a free IDE - MPLAB® (complete with programming and debugging facilities) • Can get free sample chips (6 of each type) from Microchip every 2 months

  3. PicKit components • Comes with 2 microcontroller chips - the PIC12F675 and PIC16F684 • Supports other 8 and 14-pin Flash PIC® microcontrollers • Board has 8 LEDs, a potentiometer, input jumpers, and a push-button switch • Additional components can be added to the board • Additional I/O facilities can be added via daughter boards such as the PICTail

  4. Using the PicKit for ICE 4MI • Mike Devoy has developed a set of activities (see resources slide for URL) • Can be used to cover assembly, computer architecture, debugging expectations • Teach assembly, microcontroller architecture, using a debugger and IDE, and using the PicKit to program a microcontroller • Build up to controlling a traffic light intersection (or many other applications)

  5. Assembly • Low-level programming • Common misconceptions • More difficult • More efficient • Analogy - walking instructions • Instructions versus statements • Instructions consist of an opcode (specifies the operation) and 1+ operand (parameter)

  6. Resources - Websites • Mike Devoy’s ICE4M website - http://doyle.wcdsb.edu.on.ca/ICE4MI/index.htm • Microchip - http://www.microchip.com
